A three-phase active rectifier is proposed for a wind power application. The wind generator delivers threephase output at voltages from 100 V to 500 V in proportion to speed, at frequencies of ∗ to ∗ . The power follows the cube of the speed and will be 1 MW when the output is 500 V. The active rectifier delivers energy from the generator output into a large capacitor bank. From there, an inverter processes it for grid connection. The capacitor bank is intended to maintain a nearly fixed de voltage. • Draw a circuit that meets this description. Isolation is not required. • What capacitor voltage do you suggest for this converter?Page 2 of 2 • What value of capacitor will keep the bus ripple below 5% peak to peak over the 100 V to 500 V stated input range? The inductors have been sized correctly for low ripple and good sinusoidal current tracking.
